Trying to find a log of when HOT CORNER "Put Display to Sleep" is triggered

Anyone have experience with tracking sleep events? Trying to specifically track when a user triggers the HOT CORNER for "Put Display to Sleep".

​

Trying to find a date time stamp log of each time this occurs.

​

In terminal I can:

log show --style syslog | fgrep "[powerd:sleepWake]" 

But I dont see any reference to "Put Display to Sleep"

HALP?
